The Expedition 74 crew explored how residing in house impacts the mind and blood circulation on Friday to make sure crews keep wholesome and guarantee long-term mission success. The Worldwide Area Station residents additionally targeted on spacewalking instruments and science {hardware} upkeep wrapping up the week.
NASA Flight Engineer Chris Williams started his shift on Friday accumulating his blood and urine samples for evaluation then stowing them in a science freezer. Afterward, Williams participated in a pair of checks to doc potential space-caused adjustments to mind construction and efficiency for the long-running CIPHER investigation. The primary take a look at measured his spatial cognition, or means to orient himself in weightlessness, whereas the second take a look at recorded his reactions as he practiced Canadarm2 robotic arm maneuvers throughout a pc simulation to seize a cargo spacecraft. Medical doctors will use the outcomes to guage cognitive efficiency and develop instruments to observe and shield the mind in microgravity.
Station Commander Mike Fincke of NASA and Flight Engineer Kimiya Yui of JAXA (Japan Aerospace Exploration Company) took turns learning how blood flows from the mind to the guts to know cerebral and cardiac effectivity in house. The duo wore electrodes and sensors on their neck, collarbone, and ribs measuring blood move and quantity adjustments which will result in space-related cardiac points similar to blood clots or arterial stiffness.
Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev additionally explored vascular well being sporting chest electrodes and blood strain cuffs on the arms, wrists, and fingers for his or her house company’s Endothelium human analysis experiment. They had been learning how the internal lining of blood vessels works to maintain blood flowing easily, regulate strain, and stop clots in crew members. Medical doctors are monitoring how weightlessness and house radiation have an effect on a cosmonaut’s arteries, blood strain, and coronary heart throughout a spaceflight.
NASA Flight Engineer Zena Cardman was again contained in the Quest airlock on Friday organizing spacewalking instruments and sporting digital actuality goggles coaching how you can function a spacesuit emergency jetpack. The jet pack, formally referred to as Simplified Support For EVA Rescue, or SAFER, permits a spacewalker to maneuver safely again to the orbital outpost within the unlikely occasion they turn out to be untethered.
Roscosmos Flight Engineer Oleg Platonov finalized an in a single day pictures session that mechanically photographed Earth landmarks in near-ultraviolet wavelengths in the course of the crew’s sleep shift. Subsequent, Platonov changed a vacuum pump and transferred liquids throughout commonplace orbital plumbing upkeep. Lastly, the first-time house flyer checked video recording gear and formatted video reminiscence playing cards wrapping up his work week aboard the orbiting lab. The Expedition 74 crew members will name right down to members of the family, share presents and meals, and rejoice Christmas and New 12 months’s Eve in orbit.
Pending additional mission updates in December this would be the final Worldwide Area Station weblog submit of 2025. The subsequent common weblog replace is deliberate for Monday, Jan. 5, 2026. You may also go to nasa.gov/station on the internet or @space_station on X, ISS Facebook, and ISS Instagram on social media for the newest mission info.
